I make the point that many U.S. nuclear plants could experience disasters more severe than those they were designed to withstand, and argue that the NRC should require plants to be hardened against these more severe events.

“I make the point that many U.S. nuclear plants could experience disasters more severe than those they were designed to withstand, and argue that the NRC should require plants to be hardened against these more severe events.”

Good point of which is obvious to most everyone in the world today. Only a fool would argue that.
Also obvious and well documented is the fact that many of the Nuclear Reactors in The US where not built as designed… Some even have what are now considered design flaws. We see several such disclosures each year on the NRC website.
A good example of many is the Diablo Canyon Nuclear Reactor Power Plant.http://en.wikipedia.org/wiki/Diablo_Canyon_Power_Plant :
In September 1981, PG&E discovered that a single set of blueprints was used for these structural supports; workers were supposed to have reversed the plans when switching to the second reactor, but did not. According to Charles Perrow, the result of the error was that “many parts were needlessly reinforced, while others, which should have been strengthened, were left untouched.” Nonetheless, on March 19, 1982 the Nuclear Regulatory Commission decided not to review its 1978 decision approving the plant’s safety, despite these and other design errors.

Actually this was noticed and reported during construction of the plant. Covered up with creative coercion and all.

Anyhow why are these discussion based on the false premise that these Nuclear Reactor power plants where built as designed when its documented all over the place they where not. Who would argue this?
